They swim by rotating slowly and changing directions often. If the Paramecium comes upon an obstacle, it stops, swims backwards, and then angles itself forward on a slightly different course.
I. FUNCTION AND TYPES OF MUSCLE. Locomotion: One of the most obvious functions of muscle tissue is locomotion. When muscles contract, the fibers pull or relax bones to which they are attached, thus causing locomotion. Muscle contraction is also the primary means of moving lymph in the lymphatic vessel.The circulation and return of venous blood is also partly dependent on muscle contraction..
